Hot rolled coil packaging bag sealing device

Abstract

The hot-rolled coil packaging bag sealing device is installed on one side of the C-hook opening direction and is used to automatically seal the packaging bags at the hot-rolled coil bagging station. It includes a linear guide rail (1), a common slider (2), a powered slider (3), a bag mouth tensioning device (4), a bag mouth pressing device (5), and a sealing device (6). The hot-rolled coil packaging bag sealing device automatically completes the packaging bag sealing work by aligning the powered slider and the linear module to the bag mouth. The equipment has a simple structure and good reliability. It not only liberates workers from harsh working environments and reduces the factory's production accident rate and human resource costs, but also uses sewing instead of buckles to make the sealed bag mouth tight and prevent it from falling off, avoiding quality and safety problems caused by buckles slipping down and the bag surface falling off. The realization of automatic sealing greatly improves work efficiency.
